Opis:
IED (Improvised Explosive Device) – those special type of mines have occurred in the last decade with particular intensity in the recent Afghan conflict. Due to their structure and the use of large weights of explosives, the improvised explosive devices pose very high risk on any wheeled AFVs. There is a need to have some logistic solution, to security transport of damaged AFV. Polish army needs a new semi- trailer, which would be able to transport damaged AFV on it, from Afghan to Poland, by special cargo airplane, call "Rusłan". Although this paper does not cover mounting of the loaded flatbed to the deck of the aircraft, this subsection analyzes the way how the crew of AN 124-100 aircraft fixes the AFVs during the flight. This study is the result of the research and development project No.O R00 0085 12 "Ancillary flatbed for loading of damaged AFVs ROSOMAK on board of the plane." This paper presents the results from execution of the conceptual works related to the ancillary flatbed construction concept. The construction of technology demonstrator commences on the basis of a scientific and industrial consortium (Military Institute of Armour and Automotive Technology-Air Force Institute of Technology -CELTECH-HYDROMEGA).

Opis:
Development of the 8-wheeled military vehicle computer model allows for motion simulation in various terrain conditions, as well as it serves assessment of selected dynamic parameters at specified extortions. Out of a number of the currently available professional software programs for dynamic and kinematic analysis of multi body systems, such as e.g.: DADS, ADAMS, SIMPACK, MEDYNA or NEWEUL, the DADS program has been used for modelling the wheeled vehicle. In the first phase, the model data (inter alia position of the main and local coordinate systems, geometrical dimensions, inertial and weight parameters, and also damping and elastic characteristics) is entered and presented in a form of a group of elements using the graphic interface DADS Model. As the next step, the system of differential equations that describe motion of the model is generated, using the second type of Lagrange equation. Then, position, velocity and accelerations of individual elements of the system are determined as well as their mutual interaction (forces, moments). The modelling results may be presented in a form of time processes of selected quantities, or by using computer animation illustrating behaviour of the entire system from any point of view. Such a proceeding has been conducted with reference to research and development project of Ministry of Science and Higher Education (MNiSzW) No. R0000502. As part of its implementation, a model has inter alia been constructed using a multi-body-system class of software. The model has also gone through its experimental verification process basing on a test of a double change of traffic lane recommended by ISO standards.

Opis:
Experimental research studies of vehicles are of high cognitive importance. However, they are expensive, time-consuming and sometimes dangerous, especially when they refer to edge safety parameters of a vehicle motion. Their scope can be limited if researchers conducting the studies have at their disposal a mathematical model of the vehicle motion and dynamics and a simulation program allowing for carrying out research in „virtual space. " A start-up of the simulation process requires gathering a relevant and require amount of data. If the simulation research studies that have been conducted are used for experimental verification, it is essential to obtain them to carry out a „package" of a series of experiments and a detailed design documentation analysis. Such a proceeding has been conducted with reference to research and development project of Ministry of Science and Higher Education (MNiSzW) No. R0000502. As part of its implementation, a model has interalia been constructed using a multi-body-system class of software. The model has also gone through its experimental verification process basing on a test of a double change of traffic lane recommended by ISO standards. The developed model allows for changing the values of a specific parameter in „Parameters" options - in the main window of the model.

Opis:
The paper shall present results of simulation research studies performed using a simulation model of a vehicle in which ABS and EBS system were taken into consideration as well as hydropneumatic suspension. A decision was made to conduct the simulation studies following three tests: circumferential fixed motion; emergency braking in curvilinear motion; stepping extortion on the steering wheel. As a result of performed simulation studies, more than 30 physical quantities were recorded describing the curvilinear motion of the AFV vehicle. The following were selected for presentation in listings: motion trajectory; progress of the value of lateral and side acceleration of the vehicle centre of inertia; progress of circumferential velocity values of driving wheels (essential at braking); progress of the vehicle velocity values recorded in the vehicle's centre of inertia and in places corresponding to positions of driving wheels; and progress of the values of vertical reaction forces under the driving wheels. Catalogue of the parameters being changed for the simulation is looked up to real objects and trends occurring in the changes being introduced. Paper presents progress of the value ofverticalforce in different conditions and vehicle motion trajectory. It also shows general diagram of hydropneumatic suspension system in view of the vehicle and diagram of hydropneumatic suspension system.

Opis:
The paper shall present the way for building a model for simulation studies of the wheeled armoured fighting vehicle with hydropneumatic suspension of driving wheels axles. Thus developed model shall be used to conduct simulation studies in the area of the vehicle safety. The scope of terms and conditions for applications of hydropneumatic suspensions in wheeled armoured fighting vehicles is justifled due to a number of their advantages, such as: progressive characteristics of elasticity provides great driving comfort with a small load, as well as apossibility of placing a considerable load on the vehicle (the requirements are mutually exclusive in classical suspension). Compressed nitrogen, sealed in the sphere using an elastic diaphragm, is approximately six-fold more flexible than steel springs elements at static load of the suspension, which provides high level of driving comfort; apossibility to lower the height of the vehicle by changing the road clearance which effects in e.g. higher availability for airborne transport and soon. However, they are not free from disadvantages; therefore, it is the studies of their justified use, especially related to traffic safety, that should have a final say in individual cases. The here to presented model of hydropneumatic suspension and the vehicle motion model are applied to assess dynamic capabilities and evaluate the real object motion safety.

The model has also gone through its experimental verification process basing on a test of a double change of traffic lane recommended by ISO standards. Developed simulation model of vehicle became to a considerable degree parameterized, this means that it allows to change of the values of the defined parameter in the options ..Parameters" - in the main model window. As a result of performed initial simulations computer basing on the above simplifying results assumptions, that model reflects real object in the certain range, however requires a further development looking for a fuller model verification in aspect of the particular values obtained in real measurements, that will be continued in the later stages of work. Additionally, for the purpose of the presentation of the work first stage results to ,,the media", computer visualization of the vehicle movement was made in the form of *.avi files.
Badania eksperymentalne pojazdów mają bardzo duże znaczenie poznawcze. Są jednak drogie, czasochłonne i niekiedy niebezpieczne, szczególnie jeśli dotyczą granicznych parametrów bezpieczeństwa ruchu pojazdu. Ich zakres może być ograniczony, jeżeli prowadzący badania dysponuje modelem matematycznym ruchu i dynamiki pojazdu oraz programem symulacyjnym umożliwiającym prowadzenie badań w „przestrzeni wirtualnej". Uruchomienie procesu symulacji wymaga zgromadzenia odpowiednie, wymaganej ilości danych. Jeśli prowadzone badania symulacyjne będą wykorzystywane do weryfikacji eksperymentalnej, do ich pozyskania niezbędne jest przeprowadzenie „pakietu" szeregu eksperymentów oraz szczegółowej analizy dokumentacji konstrukcyjnej. Takie postępowanie zostało przeprowadzono w związku z projektem badawczo-rozwojowemu MNiSzW nr R0000502. W ramach jego realizacji zbudowano, między innymi, model z wykorzystaniem oprogramowania klasy multi body system. Model tez został poddany procesowi weryfikacji eksperymentalnej bazując na teście podwójnej zmiany pasa ruchu zalecanym przez unormowania ISO. Opracowany model symulacyjny pojazdu został w znacznym stopniu sparametryzowany, to znaczy umożliwia zmianę wartości określonego parametru w opcjach „Parameters" - w oknie głównym modelu. W wyniku przeprowadzonych wstępnych symulacji komputerowych bazujących na ww. założeniach upraszczających wynika, iż model odzwierciedla w pewnym zakresie obiekt rzeczywisty, nie mniej jednak wymaga dalszego dopracowania pod kątem pełniejszej weryfikacji w aspekcie uzyskanych podczas pomiarów określonych wartości, co będzie kontynuowane w dalszych etapach pracy. Dodatkowo, w celu „medialnej" prezentacji wyników I etapu, dokonano komputerowej wizualizacji ruchu pojazdu w postaci plików *.avi.

Opis:
Armoured Fighting Vehicle (AFV) personnel are being subjected to high ambient temperatures, humidity and radiant heat loads for hours during deployments in the hot dry desert or warm humid tropical environment. The heat stress is even worst while operating the AFV in Nuclear Biological & Chemical (NBC) Protection mode. Maintaining crew 's physical and cognitive performance amidst all of the stressors of the battlefield is a huge tash. However, if the heat stress imposed by exposure to the climatic extremes of the environment can be controlled with the use of a microclimate cooling system then this allows the soldiers to remain focused on other critical tasks. Life Support System (LSS) is an integrated Microclimate and/or Individual Crew Cooling System (ICCS) integrated with NBC Protection system. The use of LSS or LSS that is complimented by Auxiliary Power Unit (APU) on modern AFVs ensures to the mounted soldiers the ability to maintain safe body temperature. This session will discuss the efficiency of LSS and LSS-APU on AFYs.
